Latest Headlines

BARCELONA, Spain--T-Mobile US CTO Neville Ray said that 5G networks will mainly involve new uses of spectrum to address continued expected growth in mobile data usage and different uses cases, including from the Internet of Things. At the same time, Ray cautioned that there is no need to rush to 5G networks today, as LTE and LTE Advanced networks still have a great deal of capabilities that carriers can tap.

T-Mobile US' latest uncarrier event--held at Seattle's Paramount Theater--was rife with news about the operator's network, including the fact that it has extended its LTE footprint, has more cities with multiple LTE spectrum bands and has broadened voice over LTE (VoLTE) availability.

T-Mobile US signed a long-term managed services agreement with Ericsson, which will supply the operator with its Service Agility package, including unified charging, billing, order management, product catalog and customer relationship management (CRM). The update will cover all branded T-Mobile and MetroPCS customers.

BARCELONA, Spain--Freeing up the 1755-1780 MHz block through spectrum sharing will not only aid U.S. mobile operators that desperately need additional frequencies for mobile broadband but it will also aid spectrum harmonization efforts across the Americas, said Neville Ray, T-Mobile USA CTO.

There is an obvious disconnect between MetroPCS and its suitor T-Mobile USA when it comes to Rich Communication Services (RCS) and voice over LTE (VoLTE). Either MetroPCS' efforts will ultimately be in vain once the merger of the two operators is completed or, possibly, T-Mobile will employ lessons learned from MetroPCS' experiences and use those to rapidly introduce a host of groundbreaking new services.

T-Mobile and Metro PCS' combined company will have 76 MHz of total spectrum in the top 25 major metro areas, and T-Mobile will also gain some new telecom infrastructure, such as some 6,000 distributed antenna system (DAS) nodes that MetroPCS has deployed. FierceBroadbandWireless Editor Tammy Parker recently spoke with T-Mobile CTO Neville Ray regarding MetroPCS, DAS and spectrum.
